Final answer:

The process of aging involves diverse biological, cognitive, and psychological changes that vary across societies and over time.


The perception and experience of aging vary from one society to another and within a given society over time.

Biological changes certainly occur as we age. The first signs are probably in our appearance. Our hair begins to turn gray, our (male) hairlines recede, and a few wrinkles set in. The internal changes that often accompany aging are more consequential, among them being that (a) fat replaces lean body mass, and many people gain weight; (b) bone and muscle loss occur; (c) lungs lose their ability to take in air, and our respiratory efficiency declines; (d) the functions of the cardiovascular and renal (kidney) systems decline; (e) the number of brain cells declines, as does brain mass overall; and (f) vision and hearing decline.

Cognitive and psychological changes also occur. Learning and memory begin declining after people reach their seventies; depression and other mental and/or emotional disorders can set in; and dementia, including Alzheimer's disease, can occur.
